Ensuring Product Reliability: Understanding IP Ratings for Environmental Protection
The Ingress Protection (IP) rating is a global standard (IEC 60529) that defines how well an electrical enclosure is sealed against dust and moisture. The two-digit code is a crucial indicator of a product’s durability in real-world environments—the higher the numbers, the better the protection.
The first digit rates protection against solids (dust), and the second digit rates protection against liquids (water).
Common IP Ratings Explained:
- IP54 – Dust & Splash Protected: Protected from most dust ingress and safe from water splashes from any direction. Common for indoor equipment that needs basic protection.
- IP65 – Dust-Tight & Water Jet Protected: Completely sealed against dust and can withstand low-pressure water jets. Ideal for outdoor use and industrial wash-down areas.
- IP67 – Dust-Tight & Submersible: Completely dust-tight and can be temporarily submerged in water (up to 1 meter for 30 minutes). Used for equipment that may face flooding or temporary immersion.
- IP68 – Dust-Tight & Continuously Submersible: The highest level of practical protection, indicating it is dust-tight and designed for long-term immersion under specified pressure.
